I enjoy the ease of listening to a wide variety of music through Deezer Premium Plus (320kbps) via Sonos but I am wondering if I could boost the sound quality of the Sonos Playbar feeds coming from Blu-ray and Freesat by using an e.g. Arcam irDac in between them and the Playbar?
If the answer is yes then how do I overcome the problem that the Sonos Playbar only has an optical in?
Option 1: link sources to irDac and then its analogue out into an Analogue to digital converter to link to Playbar.
Option 2: link sources to irDac then use its digital coax out into a digital coax to optical converter to link to Playbar.
Option 3: give up on the idea as the work arounds will mess up the signals.
Option 4: this is where you come in
Thanks in advance for your input.
